COUPLING MEANS FOR VEHICLES.

Specification of Letter; Patent.

Continuation of application Serial No. 544,054, filed February 15, 1910. This application filed January 13,

To all whom it may concern Be it. known that I. Part. HANSMANN, a citizen of the United States, residing at Long Prairie, in the county of Todd and State of Minnesota, have invented certain new and useful Improvements in Coupling Means for Vehicles, of which the following is a specification.

My invention relates to improvements in coupling means for connecting two or more vehicles arranged one behind the other, its

object being particularly to provide improved means for controlling the travel of each vehicle to allow it to travel in an offset path as in connecting a plurality of binders and causing each binder to cut a separate swath.

To this end my invention consists in the features of construction; combination and arrangement of parts hereinafter described and claimed.

In the accompanying drawings forming part of this spe ification, Figure -1 is a perspective view of a portion of the front end of a binder and connected draft pole fitted with my improvements; Fig. 2 is a perspective view of a portion of a support for the pole adjusting mechanism; Fig. 3 is a plan view of a pole and connecting parts; Fig.4.

is a detail broken away of a portion of the controlling mechanism; Fig. 5 is a section on line a:-:r of Fig. 3; Fig. 6 is a plan view of a plurality of binders with my improved features arranged in connection therewith; and Fig. 7 is a plan view of a draft pole broken away illustrating the action of the pivotal supports for the adjusting screw where the apparatus is subjected to a particularly heavy strain.

In the drawings A represents the framework of the vehicle to be drawn and B the draft pole. The pole B has pivotal support on a cross bar 2 by means of a vertical pivot 3 passing through the cross bar and through straps 4 extending rearwardly from the top and bottom faces of the pole. Having pivotal support 5 upon the cross bar alongside of and interspaced from the pole is a forwardly extending bar 6.. Pivotall'y supported in brackets 7 on the inner side of the free end of the bar 6 is a nut 8 in which a ,rod or shaft 9 has journal support. The inner end of the rod 9 extends slidably through a nut 10 pivoted in the outer ends of the Serial No. 602,507.

brackets 11 carried by the pole. The opposite end 12 of the rod is threaded through a nut 13 pivot-ally supported in the outer ends of brackets 14 extending from the adjacent side of the pole. The inner end of the rod has pivotal connection 15 with a rod 16 which in turn has pivotal connection 17 with a rod 18 having support 19 upon the binder frame. The rod 18 carries a handle 20 adj acent to the drivers seat 21. The rear end of the rod 16 has slidable support from the cross bar 2 through the medium of a rod 22 pivotally connected with the rod 16 at its upper end and slidable at its lower end in a collar 23, the collar 23 having pivotal support 24 upon the rear side of the cross bar. The rod 22 is held in adjusted positions in the collar by a suitable screw 25. The cross bar is connected f with the binder frame through the medium of a draw-bar 26 which draw-bar has horizontal pivotal connection 27 with the cross bar and-28 with the binder frame. One end of the cross bar is further connected with the binder frame by a hook 29 in the cross bar and extending through the eye 30 in the binder frame. The binder frame is adapted to be tilted through the medium of lever mechanism 31. The means for attaching the cross bar to the binder frame and for tilting the binder frame are not claimed as a part of the present invention, being embodied in anotherv application.

In operation, where it is desired to set the pole so thatthe binder will travel to one side ofthe machinn in front it is only necessary for the driver to turn the handle 20 to screw the rod 9 forwardly or rearwardly through the nut 13 to-set the pole at the desired angle with the cross bar. turned in either direction to cause the machine to travel to either side of the machine in front.

In Fig. 7 is illustratedthe pole slightly sprung as where the binders come in contact with some obstruction or strike an unusually heavy growth of grain.- Any such extraordinary springing of the pole is prevented from binding the adjusting mechanism by reason of the rod being threaded through'a pivoted nut 13, and being journaled in a similarly pivoted 'nut 8 and slidable through the nut 10.

One of the important features of the invention is the pivotal support for the collar Patented Dec. 31,1912.

The pole may thus betlti til

wh ch allows the rod or arms 16 and 18 to be horizmitally swung as well as vertically adjusted to accommodate them. to (lif tercut constructions of binder frames.

T his application takes the place of abandoned application Serial Number 544,054.
